Consider that:

• Problem cannot be fixed. The most obvious solution was double the blocksize, and this upgrade was stopped. Segwith was promised as the solution, but its adoption is frozen so it isn't solving nothing. Last solution is lightning network, but is still is in test phase, a version for massive adoption is still far from now.
• Situation in november was caused by the old bitcoin cash difficulty algorhitm, that has temporaneously stolen miners. When miners came back, situation turned to normality.
  Now, Bitcoin simply is slowing down because it is overheated. No miners scaping to Bitcoin Cash. The problem is that there are too users for the network. At the moment, simply bitcoin cannot handle this transaction volume.

So in my opinion the solution cannot be 100% good for BTC. Bitcoin cash is mooning and this situation won't completley reverse back in a couple of days...
